We present recent results from KLOE on the dynamics of η → πππ decays, as well as searches for rare η decays, including a new determination of the η → π0γγ Branching Ratio. We also present a preliminary result on the ratio BR(φ → η′γ)/BR(φ → ηγ), a quantity related to the η − η′ mixing and the gluonium content of the η′. All results are obtained from the analysis of 450 pb−1 integrated luminosity from 2001–2002 runs.

Abstract
We present recent results from KLOE on the dynamics of η → πππ decays, as well as searches for rare η decays, including a new determination of the η → π0γγ Branching Ratio. We also present a preliminary result on the ratio BR(φ → η′γ)/BR(φ → ηγ), a quantity related to the η − η′ mixing and the gluonium content of the η′. All results are obtained from the analysis of 450 pb−1 integrated luminosity from 2001–2002 runs.File in questo prodotto:
